If the supervisor.childopts property value contains the following setting, delete the setting:

-Djava.security.auth.login.config=/etc/storm/conf/storm_jaas.conf

Retain any other settings in the supervisor.childopts box.

Browse to Services > Storm > Configs under the Advanced tab. In the Advanced storm-site section, add or update the following settings for worker.childopts:
